What one person calls another while trying to subvert the other's intelligence, often in a public forum.

The attacker may account for the superfluous "o" by claiming to be of French heritage, but no one will believe him and will enjoy the irony of misspelling "genius" while trying to undermine another's intelligence.

A petty member of the forum will point out the mistake and may create a new definition for "genious" at Urban Dictionary.
